The correct answer for this question would be option A. When the thermal energy in a hot iron flows into a shirt, what we can possibly say about this situation is that, the iron is warmer than the shirt. The transfer of heat from the iron to the shirt is called heat conduction. Hope this answer helps.

Answer:

a) The hot iron is warmer than the shirt.

Explanation:

Thermal energy always flows from a hot object to a cold object.

This process is similar to water flowing from a higher level to a lower level.

In the given question, since the iron is hot, it has greater thermal energy compared to the shirt. So heat flow is from the hot iron to the shirt.

( like during the ironing of a shirt).

A 26 kg child is coasting at 2.0 m/s over flat ground in a 5.0 kg wagon. The child drops a 1.5 kg ball from the side of the wago

RoseWind [281]

Answer:

Final speed = 2.067 m/s

Explanation:

We are told that the child weighs 26 kg.

Also, that the wagon weighs 5kg.

Thus,initial mass of the child and wagon with ball is;

m_i = 26 + 5 = 31 kg.

Also, we are told that the child now dropped 1.5 kg ball from the wagon. So,

Final mass is;

m_f = 26 + 5 - 1 = 30 kg

Now, from conservation of linear momentum, we know that;

Initial momentum = final momentum

Thus;

m_i * v_i = m_f * v_f

Where v_i is initial velocity and v_f is final velocity.

Making v_f the subject, we have;

v_f = (m_i * v_i)/m_f

We are given that initial velocity v_i = 2 m/s

Plugging in the relevant values, we have;

v_f = (31 * 2)/30

v_f = 2.067 m/s

skelet666 [1.2K]

Answer:

Dalton's atomic theory

Explanation:

Dalton's atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings. This theory was based on the law of constant composition and the law of conservation of mass. Also, this theory explains the matter in terms properties of atoms.

A lizard climbs up a building 15.5 m and then turns around and goes down the bulding 23.7 m. This takes the lizard 31.5s. what i

alexandr1967 [171]

The average velocity of the lizard for the whole journey is 0.26 m/s Down.

<h3>What is average velocity?</h3>

The term average velocity has to do with the velocity of the lizard for the whole journey. We can see that the downward displacement is greater than the upward displacement.

Thus;

Velocity = displacement / time = 23.7 m - 15.5 m/31.5s = 0.26 m/s Down.

Thus, the average velocity of the lizard for the whole journey is 0.26 m/s Down.
